BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 400,272, dated March 26, 1889.

Application filed February 13, 1889. Serial No. 299,717. (No model.)

l" all whom, it may concern.'

Be it known that I, J UsTUs A. TRAUT, a citizen of the United Stat-es, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

My invention relates to improvements in bottle-Stoppers of the class .which have an expansible portion within the neck of the bottle, and the chief object of my invention is simplicity and economy in construction.

In the accompanying drawings, Figure 1 is a plan view of my bottle-stopper. Fig. 2 is a vertical section on line af of Fig. 1, together with a portion of a bottle, the central member of the stopper being shown in elevation. Fig. 3 is a plan view of the cap-plate of said stopper. Fig. 4 is a front elevation of my bottle-stopper with a slight modification, and Fig. 5 is a side elevation thereof.

6 designates the cap-plate designed to rest upon the mouth of the bottle'A and provided with a central oblong orilice, 7, (most clearly shown in Fig. 3,) and with two downwardlyprojecting handles, 8 8.

9 designates a plug centrally perforated and provided with a conical lower end, 10.

11 isa cylindrical block of rubber or equivalent expansible material, which is also centrally perforated, and 12'designates a bolt having a flat shoulder under its head at its lower end and a flattened shank, 13, at its up-` per end, the edges of which are threaded. The` body of said bolt passes through the cylin-` drical block and conical-ended plug, while its iiattened shank extends through the oblong opening 7 in the cap-plate 6 and is provided with the thumb-nut 14.

In the construction shown in Figs. 1, 2, and

3 I intend to form the cap-plate 6 and nut 14 of sheet metal, and the conical-ended plug 9 of a separate piece of proper material-as, for instance, wood. If desired, however, the cap-plate 6 and nut 14 may be made of cast metal, in which case the conical-ended plug or port-ion maybe formed in one and the same piece with the cap-plate 6, and in skeleton form, as shown by the skeleton plug 15 v in Figs. 4 and 5, said plug having the conical lower end, 10, substantially as in the construction first described.

In operation the stopper is inserted within 4 Vexpands the cylindrical block 11 within the mouth of the bottle to firmly close the same, as in ordinary Stoppers of this class. Turning the nut in the reverse direction will loosen the stopper.

I am aware of ythe prior patent to myself,

as well as patents to others, for internal bottle-stoppers in which an elastic block is eX- panded within the neck of the bottle under the iniuence of pressure against a cone face, and I hereby disclaim the same.

I claim as Iny invention- The herein-described bottle-stopper, consisting of the cap-plate provided with an oblong opening and handles, a conical-ended plug, an expansible block, the bolt 12, having a flattened shank, and the thumb-nut 14 secured thereon, substantially as described, and for the purpose specified.
